Issue Description

I have newly installed Jetpack 6.0, and realsense-viewer. But found that D455 and D435i cannot be detected at all. While D435 can be detected. Any idea why is this happening? And how to resolve this issue?

Best, Samuel

Hi @HappySamuel When using JetPack 6, the RealSense MIPI driver at the link below needs to be installed in order for HID type cameras (ones with an IMU) to be supported on a USB connection.

I would recommend downgrading your JetPack version to 5.1 if possible to achieve HID support without the driver.

Hi @MartyG-RealSense

Thanks for your response. Regarding your suggestion on downgrading Jetpack version, i prefer not to, as isaac_ros on Jetpack 6.0 provides multi-cam support, comparing to previous Jetpack version. By the way, I saw a post that stated downgrading the d435i firmware version to 5.13.0.50 can work on Jetpack 6.0. What's the main difference between two version?

Currently, i am going to test downgrading the d455 firmware verison to 5.13.0.55 and see if it can work on Jetpack 6.0 or not.

Best, Samuel.
